Are you working with a polyester crepe fabric? Or is it a natural crepe? It will make a significant difference...If it is polyester, you'll need to use iDye Poly (http://jacquardproducts.com/idye.html). This dye requires high temperatures for good color. Your best bet will be to tie your fabric VERY TIGHTLY and submerge it in a boiling dye bath. This should work well. The dye will not be hot enough if you try to put it in a squeeze bottle. Some people apply their poly dye through a squirt bottle and then microwave the fabric (making sure it is wet and covered so as not to set it on fire). I myself have not tried this...If you are working with a natural fiber, tie-dyeing will be much easier. You can use Procion MX dyes (http://jacquardproducts.com/procion-mx.html) in a squirt bottle, just like you would a T-shirt.
